Description Official Replacement Cartridges for Marineland Penguin BIO-Wheel Filters Keep your Marineland Penguin BIO-Wheel Filter 100 or old style Penguin BIO-Wheel Filter Mini performing at its best with these official Rite Size A replacement filter cartridges. Each box contains 6 pre-assembled cartridges that slide easily into place for fast, dry, and effortless replacement without any complicated setup or assembly required. Superior Mechanical and Chemical Filtration Each cartridge combines two powerful filtration methods in a single convenient unit. A double-thick polyfiber pad on one side mechanically traps dirt, debris, and waste particles before they can cloud your water. On the other side, Black Diamond Premium Activated Carbon removes discoloration, dissolved organic pollutants, and odors through chemical filtration. A patented ribbed backing ensures even distribution of carbon throughout the cartridge for maximum water to carbon contact and consistently clear, clean water. Easy Color Coded Sizing Marineland Rite Size packaging is color coded to make choosing the correct replacement cartridge simple and straightforward. Rite Size A cartridges measure approximately 4.5 x 4.5 inches and are specifically designed for the Penguin BIO-Wheel Filter 100 and old style Penguin BIO-Wheel Filter Mini. How to Install Rinse the new cartridge under clean water until the water runs clear before installing. Place the cartridge into the filter with the floss side facing towards the back of the filter. Cartridges slide securely into the bottom channel of the filter housing. Replacement Schedule For best results replace cartridges every 2 to 4 weeks depending on tank size, fish population, and individual maintenance habits. Never clean or replace the BIO-Wheel itself as it houses beneficial bacteria essential to your biological filtration. Made in the USA. Shipped by SLC Aquatics.
